2 Probe Specifications Cable and Probe Temperature Rating: Connector Temperature Rating: -65 C (-85 F) to 85 C(185 F) -130 C (-202 F) to 200 C (392 F). Cryogenic and higher temperature probes are available up to 1200 C - consult MTI Factory. A BNC to SMA adapter is required Accuracy 1 : ±0.01% FSR or better, of range when probe and amplifier are calibrated to a known standard at x1 range extension. Probe and Cable Interchangeability: Accurate to within ± 0.2% at X1 range extension without recalibration Pressure Rating Standard: 1400kPa (200 psig) Material: Stainless steel construction, no active internal electronics 2 Cable ength for IA, IR and PSR type Probes: 1m (3.28' ) length - see below for extension cables. Connector type probes require selection of cable assembly upon ordering 1 As range extension increases linearity decreases. Probe resolution is approximately Hz FSR. Noise increases proportionally to range extension selected. x2 range extension will decrease resolution by 2X. Increasing the averaging function will decrease noise but also decrease the amplifier's bandwidth (consult users manual). Increasing the probe s cable length will also increase system noise and decrease resolution proportionally. 2 Contact factory to increase IA/IR/PSR cable to non-standard cable lengths, or purchase the optional special low-noise probe extension cable (information on brochure). Extension cables do not require an adapter as they are male to female SMA connectors Probe Style CONNECTOR TYPE RADIA An SMA connector is built in to the probe. The cable is connected to the capacitive sensor with a connector and it exits the probe radially. RADIA PROBE SMA CONNECTOR SIDE VIEW INTEGRA EAD RADIA The cable is low-noise highly flexible silicone integral to the IR probe and exits the probe radially. BOTTOM VIEW Max. Ø= 9 CONNECTOR TYPE AXIA The cable is connected to the CTA capacitive sensor with a connector and it exits the probe axially. AXIA PROBE SMA CONNECTOR SIDE VIEW INTEGRA EAD AXIA The cable is low-noise highly flexible silicone integral to the IA probe and exits the probe axially. BOTTOM VIEW PANCAKE SQUARE RADIA The PSR probe is thin, the cable is low-noise highly flexible silicone integral to the PSR probe and exits the probe radially. PSR PROBE
